VW Up on the highway – Which engine only?

Hello together, we are about to buy an up. The car would be used mostly for the rides to work (a distance 30 km, ~25 km highway, rest of town) as well as for smaller routes across Cologne and the surrounding area. Now the question inevitably arises which engine it should be. We tend at the moment rather to the 60hp engine, but get the 75hp motor to the heart of many other (not up) drivers. Is the 75hp engine on the highway worth? That the engines are the same and is the 75hp engine, especially at the desired speed of 120 kmh – 130 kmh, similar to the 60hp engine? Is there a big difference if you want to accelerate out of a construction site of 80 kmh? If in doubt I would just switch down. Does the 75hp engine consume more petrol at 120 – 130? How do I notice with the speed of the engine? the advantages of the 75hp engine? Does it speed up faster and has more reserves? I’m not a driver who likes to turn high, I prefer to swim quietly with. You can’t really give full throttle in professional traffic anyway. I would be grateful for your experience and know. I’m still quite undecided at the moment if it’s wrong to save on the engine or if the 60hp engine is not even the better choice (noise, consumption, etc.).
